Mean percent knowledge scores in the control (black), e-module (blue) and PGY1 group (grey) at three time-points: pre-course, post-course and at 1-year follow-up. The e-module group performed better than the control group only at the post-course time-point (p = 0.003). Both medical student groups performed worse than the PGY1 group at the pre-course and 1-year follow-up (p-values = 0.003). At the 1-year follow-up, there was a smaller sample in the control (N = 50), e-module (N = 76), and PGY1 groups (N = 36)
